what exception model should I use ?

[Thomas Doerfler]

Hi,

the information in the README is no longer correct (at least for
CVS-HEAD). I will fix this ASAP.

Nevertheless, the 603e is covered in the mpc6xx stuff (e.g. in the
mpc52xx and the mpc83xx), so you should be able to use the new exception
handling anyway.

If you would use the old exception handling stuff, your port would not
be compatible with any upcoming version of RTEMS.

wkr,
Thomas.
